Patch 10.2 adds an item that lets you send Honor to alts at a certain price…
Glorious Medal of Honor is a new BoA item sold by Seltherex <Honor Quartermaster> in Valdrakken. It costs 2,500 Honor and grants 1,500 Honor to your alt. Still a bit on the expensive side, since you’re paying 1,000 Honor for every token, but at least you have a way now to funnel Honor to your alts!
